To ILZZ wh/mt it ntuty concern:

Be it known that I, Josurn S. DUNGAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Printing-Machines, of which thefollowing is a specification.

The primary object of this invention is to print separate addresses andthe proper salutation for each address on circular-letters and the like.

The invention also has for its object to print the add ress, salutation,and letter in one printingoperation and to automatically provide theproper salutation required by each address, such as Dear sir for asingular address and Gentlemen for a plural address.

In the accompanying' drawings I have shown one embodiment of theinvention in a jobprinting press in which an oscillating platen carriesthe sheet to be printed into contact with a form fastened to a bed. Ihave not considered it necessary to show a complete printing-machine, asthe general construction and operation of such machines are wellunderstood. I have therefore shown the parts only with which myinvention is immediately7 associated.

Referring to the drawings, Figure 1 is a rear view of a portion of thebed-plate of a printing-machine with my invention applied thereto. Fig'.2 isa sectional view on the line 2 E2 of Fig'. I. Fig'. 3 is a sectionalview on the line 3 3 of Fig'. 2. Fig'. 4 is a detail Vfront edge view ofthe salutation-form holder. Fig. is a sectional view on the line 5 5 ofFig. 2. Fig. 6 is a sectional view on the line 6 G of Fig. Fig. T is aside elevation (partly in section) showing as much of an ordinaryjobprinting' machine as is necessary to understand the arrangement andoperation of my invention. Figs. 8 and 9 illustrate the parts which turnthe drum carrying the printing device. Fig. l0 illustrates a printingdevice which may be used. Figs. 1l and I2 show another form of thesupport for the salutation-forms.

Referring' to Fig'. 7, the platen I5 is oscillated in any suitablemanner on the shaft 16 to carry the sheet to be printed into printingposition against a main form 1T, Fig. 2, supported on the bed-plate 18of the machine for printing the body of the letter. This form may bemade of rubber type, as shown in Fig. Q. or in any other suitablemanner.

I may employ addressforms made up ot rubber or other type orprinting-plates or other equivalent devices adapted to be fed in aproper manner to bring the addresses successively into printing positionadjacent t0 the main form. AIn the drawings, Figs. 8 to l0, -I haveshown a chain or belt made up of addressforms consisting of rubber typemounted in holders 19, which are linked together in any suitable manner.The chain of add ress-forms is arranged to travel on a rectangular drum20, which is carried by an oscillating d rum-frame 21, mounted on ashaft 22. A rod 23 is connected at one end to the drum, and its otherend is provided with a fork 24 to receive the counter-shaft Q5. A spring26 is fastened at one end to a collar 27 on the counter-shaft and at itsother end to the rod 23 at Q8. the purpose of this spring being' to holdthe antifriction-roller 29 on the rod in operative position against thecam 30 on the counter-shaft and to pull the drum back Vfrom printingposition after the printing operation has been completed. Thecounter-shaft is operated by any suitable means, and in the swingingmovement of the drum caused by the spring and cam the drum is revolved aquarter-turn to bring a new add ross-for m into printing position, andthis feeding' movement of the drum is accomplished by two arms in thenature of pawls 31 32, pivoted at 33 on a bracket 34 on the main frameof the machine. lVlien the spring 2G pulls the drum rearward from theposition shown in full lines to the position shown in broken lines inFig. 8, a projection 3Q of suitable character on the pawl 3Q engages therecess QO/ on that side of the drum which has been the back during thepreceding printing operation, and on the continued rearward movement ofthe drum against the pawl 3'2 the drum is revolved a portion of aquarter-turn, as indicated by the broken lines in Fig. S. Thereafterwhen the cam 30 moves the drinn forward a projection 31/ on the pawl 31engages the recess 20/ on the uppermost side of the drum, and on thecontinued forward movement of the drum this pawl causes the drum tocomplete its quarter-turn, moving 'from the position shown in brokenlines to the position shown in full lines in Fig. 8. The rear ends ofthe pawls behind the pivot 33 are connected by a spring 35 to hold thepawls in proper position for their work, and a lug 36 on the bracket 34projects across the pawls to prevent the spring from pulling them out ofoperative position. A safety projection 3l" on the pawl 3l is preferablyIOO IIO

provided to engage the drum in event the projection 31' fails to do so,and this insures the completion of the quarter-turn of the drum.

The invention contemplates providing a plurality of salutation-formsadapted to be shifted as required to provide the proper salutation foreach address. In this connection I have illustrated the Dear sir andGentlemen forms, which are most commonly used; but I may use singularsalutations exclusively, such as Dear sir and Dear madam, or any otherforms and Jfor printing any subject-matter that may be desired. As thesalutation LDear sir is more --often used than Gentlemen, I generallyarrange the Dear sir form normally to print at each operation of themachine and provide for moving it out ot' printing position and theGentlemen form into printing position when the plural salutation isrequired by a plural address. This order may be changed as occasionrequires by simply changing the relative position of thesalutation-forms. 'Ihe salutation-forms are supported end to end on thefront edge of a plate 37, Fig. 3, which is pivoted at 38 on thesupporting-frame 39, this frame being itselic pivotally mounted at itsupper end 40 to the back of the bed. The front edge of the plate 37 hastwo straight sections 4l and 42, angularly disposed with relation toeach other and forming the bases of contiguous segments of a circledescribed from the pivot 38, the-Dear sir form 41/ being mounted on thesection 4l and the Gentlemen form 42 on the section 42. Thesesalutation-forms may be made up of rubber type or logotypes or otherwiseand secured in any suitable manner on the plate. A spring 43, fastenedat one end 44 to the frame 39 and at its other end 45 to the plate 37,holds the plate with the Dear sir form normally in printing position andthe Gentlemen 'form out of printing position, a screwstop 46 beingprovided on the drum 39 to engage the plate 37 -for properly positioningthe Dear sir form. A bell-crank lever is pivoted at 47 on the frame 39,Fig. 2, and one arm 48 of said lever is engaged with a bar 49, pivotallymounted at 50 on a projection 5l at the side of the plate, 37 Fig. 3. Toprovide for a proper relative adjustment of the arm 48 and bar 49, thearm 48 has an opening 48 to receive the bar 49, which is screw-threadedat its outer end to receive the nuts 50', which secure the arm on thebar. I also arrange a spring 51 on the bar between the arm 48 and thenuts 52 to provide for some loss motion. The lower end of the other arm53 of the bell-crank lever is arranged opposite the end of the drum andis turned inwardly at 54, Fig. l. All plural-address forms requiring thesalutation Gentlemen are provided with an end projection 19', Fig. l0,and as the drum is carried forward from the position shown in brokenlines in Fig. 8

with a plural-address form in printing position the inturned end 54 ofthe arm 53 is'engaged by the projection 19 and moved forward with thedrum, as shown in Fig. 9. This movement ot' the arm 53 is communicatedthrough the arm 48 and the bar 49 to the plate 37, which swings on itspivot 38 and carries the Dear sir form out of printing position and theGentlemen Jform into printing position in time for the printingoperation.

When the plural address has been printed and the drum moves back to theposition shown in broken lines in Fig. 8, the arm 53 is released fromengagement with the projection 19 and the spring 43 swings the plateback against the stop 46 with the Dear sir 7 form in printing positionagain. plate is arranged to engage the frame 39 to limit the swingingmovement of the plate which brings the Gentlemen form into printingposition, and the loss motion provided by the spring 51 avoids thenecessity for a delicate adjustment ofthe lever and plate. An extension56 on the end of the drum is arranged to form a backing for theprojection 19 on the address-form to prevent the arm 53 from bendingsaid projection during the foregoing operation.

I/Vhen the singular-address forms, which do not have the projection 19,are moved into printing position, the arm 53 is not engaged and remainsstationary and the spring' 43 holds the Dear sir form in printingposition. The lower end of the holder 17, carrying the main form 17, ispreferably cut away at 17 to accommodate the plate 37, which is shownarranged in angular relation to the main form in order to clear thechain ot' address-forms and hold the salutation-form in its properposition relative to the main form and the address-form, Fig. 2.

'Ihe supporting-frame is adjusted relative to the bed of the machine toproperly position the plate 37 by the screws 57, and this frame issecured in adjusted position by the nut 58 on the bolt 59, pivoted onthe frame at 59' and projecting through a slot 60 in the bed, Figs. 5,6. By loosening the nut 58 the bolt may be permitted to swing downthrough the slot 60 to release the frame from the bed, and the frame canthen be pushed back to carry the salutation-forms out of operativeposition.

The usual sheet-holder 60, pivoted at 6l on the platen, carries a latplate 62, which covers the address-form below the one in printingposition to prevent it from printing during the printing operation.

Instead of mounting the salutation-forms in an angular relation aspreviously described I may arrange them in alinement, as shown in Figs.l1, l2. In this construction the saluand to said bar.

A screw-stop 55 on the IOO a projection 65 on one of the links, and theother parts are the same as previously described. ln this construction lprovide the sheet-holder till with a plate 627, which not only coversthe address-form below the one in printing position, but also covers thesalutation-'form not iu printingposition, as shown in Fig. l2. Thisplate (52 has an opening G6, through which the address-form iu printingposition prints, and an opening (ST, through which either one of thesalutation-forms may print while the other is completely covered by theplate. In Fig. 12 l have shown the "1)ear sir form in printingpositionand the "(entlemen7 form covered. When a plural address is brought intoprintingl position, the same operation takes place as previouslydescribed, except thatthe salu tation-forms move in a straight line (tothe left in Fig. 1Q) instead of in the arc of a circle to carry the Dearsir" form out of printing position and behind the plate 62' and move the"Gentlemen form into printing position opposite the opening 6T.

'ith this invention a circular-letter can be printed and addressed withthe proper salutation in one operation of the machine. It avoids thenecessity of separating the addresses according tothe character of thesalutation required and changing the salutations accordingly and enablesthe order of tiling the addresses, alphabetically by States or cities,by class, or otherwise, to be constantly maintained. The salutation formis properly alined to be inked at the saine time and b v the same meanswhich ink the main and address forms, and by printing the entire letterin one operation l. am able to produce a very close imitation of atype-written letter. lhe body ot' the letter may, if desired, be printedseparately and the address and salutation supplied afterward.

\\'hile the invention is particularly adapted for printing salutationson letters, it can be used for other purposes, and in referring to theprinting of salutations l do not wish to be strictly confined thereto.Nor is the invention restricted to use with a printing-machine having anoscillating platen, although this is a very desirable embodiment.
